646812 ÷ 29 
Our goal is to divide 646812 by 29.

Going ahead to step 1:
When dividing 6 by 29, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 29

Let's proceed to step 2:
The number 29 fits into 64 2 times, leaving a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 58 from 64 and we're left with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 29

Moving on to step 3:
29 can be fit into 66 2 times, resulting in a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 22.0
If we take 58 away from 66, we end up with 8.
Fetch the next digit (8) from the dividend, attach it to 8 and continue: 88 / 29

Advancing to step 4:
29 can be fit into 88 3 times, resulting in a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 223.0
If we take 87 away from 88, we end up with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 29

Step 5:
When dividing 11 by 29, we get 0 with a remainder of 11.
Use 0 as the next digit of our solution. 
Result so far: 2230.0
If we take 0 away from 11, we end up with 11.
Grab the next digit (2) from the dividend, add it to 11, then carry on: 112 / 29

Moving on to step 6:
29 can be fit into 112 3 times, resulting in a remainder of 25.
Record the quotient 3 as the next digit in the result. 
Result so far: 22303.0
Subtract 87 from 112 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 7:
29 goes into 250 8 times with a remainder of 18.
The number 8 becomes the next digit in our result. 
Result so far: 22303.8
If we subtract 232 from 250, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 8:
The number 29 fits into 180 6 times, leaving a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 22303.86
Subtracting 174 from 180 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 9:
When dividing 60 by 29, we get 2 with a remainder of 2.
The next digit of our result is 2. 
Result so far: 22303.862
If we subtract 58 from 60, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 10:
When dividing 20 by 29, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 22303.862
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 11:
200 divided by 29 is 6 with a remainder of 26.
Record the quotient 6 as the next digit in the result. 
Result so far: 22303.86206
If we take 174 away from 200, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 12:
260 divided by 29 is 8 with a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 22303.862068
If we take 232 away from 260, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 13:
When dividing 280 by 29, we get 9 with a remainder of 19.
Put 9 as the next digit of the answer. 
Result so far: 22303.8620689
If we subtract 261 from 280, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 14:
The number 29 fits into 190 6 times, leaving a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 22303.86206896
If we subtract 174 from 190, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 22303.86206896, with a leftover of 1.6e-08.
